In 2004, they topped Billboard’s classical chart for 76 weeks with their American Angels album, which tells you just how popular an all-gal quartet of early music singers can be if given the chance. Anonymous 4 has been praised for their ethereal tones and vocal virtuosity, even causing critics to stoop to the cliché of calling them “angelic,” basically because no other word will do. So, there’s probably no group better suited to present Chamber Music in Historic Sites’ annual holiday concert. Titled “The Cherry Tree,” after a British ballad from the Middle Ages, which was later adopted in Appalachia, the program features songs, ballads and carols for Christmas, and includes both medieval European and early American fare. Among the highlights are the Irish song “Be Thou My Vision”; shape-note hymns for Christmas dating from the 18th and early 19th centuries; and the group’s own version of the gospel favorite “Beautiful Star of Bethlehem.” To make the experience complete, the concert takes place in the magnificent sanctuary of St. James Episcopal Church, a 1924 architectural masterpiece known for its soaring Gothic design and awe-inspiring Judson Studios stained-glass windows. Preconcert talk at 3:30 p.m. St. James Episcopal Church, 3903 Wilshire Blvd., L.A.; Sun., Dec. 7, 4:30 p.m. $41-$49. (213) 477-2929.
